    Water pouring from harmonic balancer area on muffs

    The 488/3.7 engines were a redhead step child . A lot of mechanical shortcomings in the design. If the boat is worth the effort swap in a3.0 or 4.3

    Mercruiser Shifting Issues

    See attachment from factory manual I found it best to pull the inner core out, then push a weedwacker wire up the cable to the shift plate and tie it off, pull the cable outer sheath out through bellhousing. Use the weedwacker wire to guide the new outer cable up and around the exhaust and...

    1988 350 Stumble Problem

    When it happens check spark strength with a spark gap tester to rule it out. I suspect you have a fuel delivery or carb issue. Prob a good carb cleaning will help, but would verify fuel pressure while its acting up

    Electrolysis not a bad thing

    Would suspect the algee growth change is from something else as if stray electricity kept it at bay no one in marinas, which are known for stay current, would need bottom paint.

    Lumpy idle after carb rebuild | Holley 2300 | Volvo Penta 3.0 GS

    There may be a vacuum fitting plugged on manifold There is vacuum supplied through a small tube for the choke pull off Prob can put your gauge on there and just force the choke open Can also just tune it by ear or rpm when you go way lean and way rich it will stumble In Between these two...

    HELP I can't get my motor realigned

    That would be a good sanity check . Also seen folks us a 1" pipe or dowel which wont be tight in the coupler but allows you to insert it and look in with a flash light to see which way it needs to move. Be interested to see if the tool is wrong as that would be easiest solution. Would also...

    Help a little old lady with her little old mercruiser 120 wiring?

    I only have a gen 2 trim wiring diagram but it looks like there is a 20 fuse in the red between where it takes power off the solenoids and supplies it to the trim/trailer switches at helm and trim limit switch. Weather it was there originally or someone added a newer fuse holder to replace an...

    Overheating at idle

    the balls in thermostat housing are supposed to restrict flow of raw water to elbows, if they have debris could be passing too much water into exhaust starving the engine of cold water. Are you sucking air in at impeller if lower housing is corroded or water dam in there is damaged this can...

    proper shift bellows install.

    Manual 14 pg 4B-66 says to crimp shift bellows (zip tie is fine too) - it gives a spec for clamp to be 2.5" off the bellhousing.

    Merc prop selector

    Haven't busted either personally. Over time (many years) the pressed in rubber will slip, had several of those happen over the years. I think you are correct that the delrin will essentially act as a shear pin. You can get a spare hub sleeve for a few bucks. I keep a complete hub and thrust...

    Arcadia/Traverse Suitability?

    any of the vehicles except the 1k tow rated version will be fine. Your other thread on the Kia Telluride will work well too. What I found out when I bought my highlander is the higher tow rated versions of the Highlander (XLE) vs the lower rated ones - the difference wasn't in engine, trans...
